UNITED STATES PATENT OFFICE.

CHARLES O. BIRNEY, OF KANSAS CITY, MISSOURI.

SASH-FASTENER,

SPECIFICATION forming part of Letters Patent No. 465,517, dated December22, 18.91.

Application filed October 12, 1891.

Be it known that I, CHARLES O; BIRNEY, a citizen of the UnitedStates,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and ener, Roller, and Look; and I do declarethe following to be a full, clear, and exact description oftheinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to theletters of reference marked thereon,which form a part of this specification.

The object of my invention is to provide a combined sash fastener,roller, and lock which will do away-with the old system of cords,weights, and pulleys, and also window fasteners and locks of all kindsheretofore in use.

Afurther object is to provide such a mechanism that when applied towindows they may be raised or lowered any desirable distanee and willnot only be fastened, but securely locked at any point, so that whenrequired they may be left open at top or bottom, or both, and be securefrom burglars or other intrusion, as by the old method when completelyclosed and locked.

I attain these results by the mechanism illustrated in the accompanyingdrawings, in which- Figure I is a view of a front elevation of a window,showing the sash and jamb sufliciently cut away to expose and illustratethe invention. Fig. II is a detail view of the sash lock as sunken in arecess in the jamb to such an extent that the cogs of the toothed wheelF will operate in the recess in the rack-bar. Fig. III is a detail frontview of the sash-lock, press-button, coil-sprin g, and pressure-springsto the axle. Fig. IV is a detail view of the rack-bar. Fig. V is adetailview of the springpivot andlock-bar combined, which are operatedback and forth by pressure or release of the button.

Similar letters refer to similar parts throughout the several views.

A'represents the window-jamb, in which the sash B is operated.

B is the window-sash.

O is the metallic rack-bar or cog-rail coun- Serial No. 408,467. (Nomodel.)

' c c c are the cogs of the rack-bar, in which E is a hollow lug oncasting D, in which a lock-bar E is operated by means of the button e,the shaft e, and the coil-spring e.

E is the lock-bar, which always holds the window in locked position,except when the button is pressed in, which throws it out of lockingposition and allows the window to be raised or lowered at will.

E" is that portion of the locking-bar which holds the gear-wheel inlocked position when at rest.

e is the push-pin passing through the jamb, entering a socket in thelock-bar, and is held firmly in constant pressing condition by means ofa metallic plate firmly bolted to the jamb-and through which its head 6'protrudes. This push-pin is provided with a flange on the inside of theplate to hold it from protruding too far.

e is the protruding end of the push-pin-and is the operating-button, bypressure of which the locking device is thrown out of gear with the cogson the toothed wheel.

6" is 'a retention-plate bolted or screwed to p the jamb, which by aidof a flange on the pushpin prevents the same from freeing itself fromits position in the socket in the head of the locking-bar.

e is the coil-spring surrounding the arm of the lock-bar and fastened sothat when the the toothed wheel operates. D is a metallic frame providedwith flanges d gl for affording better provision for bolting and holdingitself in rigid position in the sunken recess of the jaml).

(Z d are flanges. 6o

button or push-pin is pressed and lock thrown these springs prevent anyrattling of the window-sash, whether in process of raising, lowering, orat rest.

In the operation of my mechanism it will be seen that the metallicrack-bar O is countersunk intothe sash just sufficient to afford smoothmovement of the sash up and down. The metallic frame is then sunk into arecess in the jamb and rigidly bolted therein, so that the cogs or teethof the gear-wheel will exactly fit into the corresponding recesses ofthe rack-bar, and this gear-wheel being held in constant pressingposition againsttherackbar by suitable parallel springs operatingagainst the ends of the gear-wheel and the ends of the axle resting inhorizontal parallel slots the gear-wheel, while never binding, yet isconstantly being pressed against the rackbar and prevents any rattlingof the mechanisni' or window, and whenever the pressureshaft .isreleased the window is firmly locked at any desired point, being capableof being locked at as (many diff-erentpoints as there are recesses inthe rack-bar. Havingplaced the metallic frame in position, a shaftextends from the outside of the jamb through .itand into a socket in theend of the locking-bar,

which, with the assistance of the coil-spring on the pivot, is movedback .and forth and the gear-wheel is locked or unlocked as desired.

Having fully described my invention, what I claim, and desire to secureby Letters Patent,

In combination with a window-sash and jamb, the rack-bar or cog-railcountersunk in the sash, the toothed gear-wheel operating loosely on anaxle in a metallic frame in conjunction with the rack-bar or cog-rail,the lock-bar and pivot-bar, a coil-spring surrounding the rp'ivot-rbarfor throwing the lock-bar into locking position,and a push-pin or buttonpassing into the jamb, having arfiangecoming in-contact withthejamb-plate to hold it firmly .in thesocket-ofthe=1ock1bar,-substantially as set forth.

In testimony whereof I have affixed'm y signature in presen ceof twowitnesses.
